Fertility Rates: Why are they so different around the world

I wrote about this topic recently for a class of mine, and I thought I would share this topic here, since it’s an issue that have interested demographers and other social scientists for a long time.

Introduction and Significance of the Study:

It has been frequently observed that women around the world today have vastly different fertility rates. Last year, a news article from CBS news suggests that the dropping birthrates, especially in developed nations, is threatening global economic growth rate.(CBS) This is indeed a worrisome issue for policy-makers, from Germany to Japan. At the same time, we note that these developed nations are also among the most densely populated regions in the world, suggesting that these nations in the past have had high population growth rates, but subsequently slowed their birth rates. At the same time, many nations in Sub-Saharan Africa have relatively low density populations and abundant agriculturally productive land (Kenya, Tanzania), yet are economically underdeveloped. In class, we spoke about the “demographic transition”, i.e. each of these countries are in a different stage of this transition from high to low birth rates (Goldstein). However, given the observation that many nations that have low birthrate already have a high population concentration, we wondered if population density in fact affects the number of children a woman will have and if other underlying factors – such as governmental actions, social norms (especially for women), and levels of economic development – will affect the number of children a women have over the course of her lifetime.

Hypothesis: Regions with high population density would have lower fertility rates; this is due to economic development over time, the role of women in society and government policies.

In this study, we looked at 3 broad geographic regions: East Asia & Pacific, Middle East & North Africa, Sub-Saharan Africa and compared their developments over time. These 3 regions were used since the cultural practices, economic fortunes, and governmental influences were vastly different and provides a good cross-sectional study for analyzing the changes in global fertility rates. We will determine if the changes in fertility rates in these three regions are indeed negatively correlated with population density and other underlying factors such as economic development, women’s employment and other factors such as the availability of contraception.

2) Data Extraction and Methods:

All data for this study came from the World Bank Data, from 2012 and 2013 depending on its availability. We utilized all available data the following variables to complete the study:

  • Total fertility rates: the average number of children that a woman is expected to have over the course of her lifetime (for 1960-2013)
  • Overall population density: total population of the country divided by its total land, in people/km^2 (for 1960-2013)
  • GDP Per Capita. The Gross Domestic Product (GDP), a measure of total national economic output, divided by the country’s population for a given year (for 1960-2013)
  • Female labor force participation rate: percentage of women active in the labor force, aged 15 or older. (for 1990-2012)
  • Contraception prevalence: the percentage of women (or her partner) who were practicing any form of contraception; for women ages 15-49. Data available only for 1990, 2000, and 2010.

In this study, we used several different prospective factors that may affect the overall population density and were associated with changes in fertility rates for women: GDP per capita, female labor force participation and contraception usage. The three regions were chosen based on their differences in changes in Total Fertility Rates, such as timing and speed of decline, in order to study what could have contribute to this different variations in their respective patterns of decline. The observed period of time was selected as the maximum number of years for which data was available to ensure that whatever correlation we observed was not do to random variations within the data set. In addition, a separate study was done for China to measure a special case of the effect of government policies on the decline in birthrates.

For the sources of data, our date ranges are from 1960 to 2013 for fertility rates, overall population density, and GDP per capita; and ranged from 1990 to 2013 for female labor participation and contraception usage. We use the largest date range available for each variable in order to more accurately determine the long-term trends for each variable.

Methodology: We decided to analyze the data by presenting the relationship between the variables in a graphical format. For readability, we divided the variables into two sets of 3 graphs each, with each graph representing a separate region. The first set of graphs presented fertility, population density and GDP per capita in each of the graphs. For the next set of 3 graphs, we presented fertility rates with women’s labor force participation and access to contraceptives. Then we calculated the correlations between the fertility rates with each of the other variables to give a more definite, mathematical result. The final graph measured specifically China’s decline in birthrate and increasing per capita income.

3) Presentation of Results:

Graphs 1-3 records data for the three regions from 1963 -2013. It measured the changes through time of fertility rates, population density and economic output. Graph 1 depicted Middle East/North African fertility, GDP per capita and population density trends over time. There were several trends common to all. First, there was a very strong negative correlation between the fertility and population density/GDP per capita in all three regions measured (a correlation between -0.8 and -0.98). Second, population density had been steadily increasing for East Asia & Pacific and Middle East, while the Sub-Saharan African density had been increasing much more dramatically. Thirdly, the most rapid phase of GDP per capita increase occurred in all regions after 2000.

For Graph 1, we saw that the fertility rate for the Middle East steadily decreased from 1960 to 1985 (6.87 to 5.88) and then had a steeper decline from 1985 to 2000 (5.88 to 3.04), and finally the decline in fertility stabilized at around 2.75. Meanwhile, the population density increased dramatically from around 10 people per square kilometer to around 36 people per square kilometer, increasing roughly linearly. Therefore, there was a strong negative correlation between population density and fertility decline in this region. Meanwhile, per capita income in the region has also increased, most significantly from 1973 to 1980 and from 2000 onward. Graphs 2 and 3 told a similar story. East Asian &Pacific fertility declined drastically from late 1960s, from 5.5 children per woman in 1968 to 1.85 per woman in 1998; economically, the region’s per capita income steadily increased until 1995, and then stagnated from 1995 until around 2002, before starting to increase drastically once again. For Sub-Saharan Africa, the decline in fertility occurred much later, starting around 1987, and had been declining at a slower pace than for the other two regions discussed. Likewise, sustained per capita increases only occurred starting around 2001.

Graphs 4-6 records data for the three regions from 1990 -2010. It measured the changes through time of fertility rates, percentage of women in the labor force and the prevalence of contraceptives. All three regions witnessed the increased use of contraception: East Asia increased from 73% using contraception to 80% usage rates; Sub-Saharan Africa from 15 to 25%. Graph 4 depicted this increase in the East Asia/Pacific region and showed a roughly steady participation by women in the labor force. Aside from East Asia, there existed strong correlation between labor force participation by women and declining birth rates (-0.95 for both Middle East and Sub-Saharan Africa). Finally, a separate graph (Graph 7) was drawn for China by plotting its decline in fertility rates over time for the purposes of examining the effect of public policy on fertility. We see that fertility rates in China declined drastically from 6.3 in 1965 to 2.71 in 1980. Declining further until 1998, and it has held steady at 1.6 since then.

4). Conclusion

This paper studied the relationship between fertility rates and population density and prospective underlying causes for changing population densities. We found that there was a clear negative correlation between declining fertility rates and each of the individual factors measured: GDP per capita, female labor force participation and the prevalence of contraceptives. However, we cannot isolate any of these individual factors and point to it as a cause for declining fertility rates. Each of these factors are not mutually exclusive and acted to reinforce one another as well. For instance, increasing GDP per capita can increase contraceptive use since more women now could afford these new products; or along the lines of Boserup, increasing population could lead to greater density and more innovations and technological changes, which in turn increases income and decreasing the fertility rates. (Boserup) And it is possible that the variables examined are the result rather than the cause of fertility decline (i.e. a demographic “dividend” from having less child dependency) (Factsheet). The causes of fertility decline were complex and this paper only sought to examine a small amount of variables that can affect it.

The effect of family planning and government measures were more open to debate. For example, in China, we saw that fertility rates has already fallen to 3 by 1980, the year the so called “one-child policy” was implemented (Moore). Thereafter, the fertility rates steadily decreased, but based on comparisons with East Asia as a whole, it appeared that this fertility decline would have taken place even without the said policy. What appeared to be more significant in causing fertility decline remained the other factors discussed, such as increasing economic performances and contraception usages.

Limitations of the study:1. Exclusion of certain countries and regions from the study. There are incomplete information (missing fertility rates etc.) for certain country’s data. Therefore, these countries are not included in the regional averages. Some of the countries excluded have very high population density and relatively high birthrates (ex. some Pacific Island states) which are both factors we are attempting to draw conclusions from in this paper. This exclusion could result in errors that can affect our conclusions based on the graph and these data, once included, may result in slightly altered correlations and possible interpretations.

  1. Numerous other factors that may affect population density and fertility rates. There are other underlying factors that can cause a decline in fertility rates other than the economic development, women’s participation in the economy or government policy. Even though fertility rates negatively correlates between each of these factors, we cannot conclusively state that fertility rates rate is caused by these factors. Other factors that may be impactful include women’s educational attainment, and increasing quality and quantity of public health services. More studies need to be done how the effects of some of these other factors may directly impact fertility rates.
  2. The factors that contribute to fertility decline are not fully independent of one another. For example, the increased distribution of contraceptives may be the result of increasing economic output as measured by increases in GDP per capita, which enabled women to purchase contraceptives in the first place. The variables measured in this study can and do influence each other. Therefore, the conclusion drawn (that a negative correlation exists between fertility rates and all the other variables), may be an oversimplification.

On Iran’s nuclear program: an alternative view

Iranian nuclear program has drawn a significant amount of international attention – and condemnation – since it was uncovered in the early 2000s. While the issue is complex and multifaceted, I believe a few points should be examined. First, why is the Iranian government desirous of a nuclear program? And do the people really want it? Second, how should the rest of the world respond to it? Are the current negotiations with Iran the best way to approach this issue? And lastly, how should we all proceed from here?

The Israeli historian Martin van Creveld once said that “Had the Iranians not tried to build nuclear weapons, they woul6a00d8341c4fbe53ef00e54f31467c8833-640wid be crazy.” Although his words may seem extreme, we need to understand what motivated the Iranian leadership to develop nuclear power, even in the face of mounting international oppositions. The Iranians’ own argument is that they need to secure their own energy needs in the form of nuclear power. This argument is hardly plausible: Iran is sitting on the world’s second largest reserves (after Russia) of natural gas. Iran’s South Pars gas field alone is estimated to contain 14×10^12 m3 of gas, around 5.6% of the entire world’s prove gas reserves. Moreover, the country contains the 4th largest reserves of oil in the world. Iran’s energy needs can largely be satisfied by its oil and natural gas, as can be seen in the chart below. iran energyIf energy security is not the real reason, then what is? The true reasons for such a program, I believe, includes the following:

  1. Scientific and cultural prestige: Let’s imagine that the Iranians do not in fact want to build a nuclear weapon (a highly unlikely assumption for reasons that I will explain later), the mere fact that Iran is capable of developing advanced technology is something that the Iranian government can be proud of. In Iran, like many other parts of the world, scientific advances symbolizes the greater progress made in a society. The Iranian government sought to legitimize itself by promoting science and technology (much like the Soviet Union spent tremendous efforts in space exploration to legitimize the ideology of Communism). The Iranian people want to see progress being made in a variety of different fields, whether it be a rocket launch or a prospective nuclear power generation plant. Iran is gaining prestige by possessing those technologies. In a sense, scientific prestige is also tied into cultural prestige. We need to remember that Iran is more of a historical civilization than a nation-state in the modern sense of the word. The Iranian people had inhabited the Iranian Plateau for thousands of millenniums, and for much of that period Iran (or Persia, as it is known for most of its history), is a leading force among the world’s nations, and not merely in technology. It is in early modern times that Iran had fallen behind. In a way, many Iranians want to regain that sense of pride which have belonged to them historically. As heirs to a rich cultural heritage, Iranians today no doubt want to relive a part of its ancient glories; developing nuclear powers along the lines of other advanced nations will symbolize a part of this regaining of prestige.Mideast-Iran-Nuclear-_Horo2
  2. Competition from regional powers: Let’s take a look at how the world appears from the position of Iran, and why its nuclear ambitions will likely lead to nuclear weapons. Geographically, Iran couldn’t be in a more dangerous position. As the map below shows, Iran is surrounded by potential or probable enemies. To its west, Iraq, despite its Shia majority (the majority religion in Iran), is embroiled in a complicated civil war with the radical Islamic State (IS). Further west, we see a similar situation in Syria, where Iran-backed government of Bashar al-Assad is fighting a multi-front war against IS and moderate rebel forces. Each of these governments, if they fall, would produce a serious threat to Iran itself; and these are just the militant organizations. Organized threats by nation-states posed a bigger problem still. In its southwest, across the Persian Gulf, the Kingdom of Saudi Arabia is ferociously anti-Iranian and possesses a powerful modern military and an alliance with the United States; other Sunni Gulf States are no more friendlier. Further to the west, Iran faces the strongest military power in the region in the state of Israel, which had spear-headed efforts to contain the Iranian enrichment program. Further to its north and east, Russia, China, Pakistan, and India are all nuclear powers. In such a dangerous neighborhood, Iran felt that by developing the bomb, it can achieve a sort of parity with the other regional and global powers, at least in part to compensate for its relatively conventional forces.
  3. Security and Geopolitical leverage: In a point related to the second one, we need to be aware of the fact that Iran really has no natural allies. Culturally, it is the product of thousands of years of Persian civilization centered in the plateau of Iran, influenced by the forces of Shia Islam for centuries (today, an absolute majority of the world’s Shia Muslims lives in Iran), and the rise of political Islam in the form of the Iranian Revolution of 1979. For good or bad, few other countries possess such a unique historical experience. While this is a point of pride for many Iranians, at the same time, this also meant that Iran cannot count on any natural allies in the sense that the UK can rely on the US or Kuwait can rely on Saudi Arabia. The allies and friends it does have among governments are less than appealing: Iraq is bogged down in a struggle of a sectarian nature between Shia-dominated government and Sunni militant Islamists; likewise Syria is fighting its seemingly interminable civil war; the militant group Hezbollah in Lebanon is considered an ally and a way for Iran to project power into the eastern Mediterranean, but is categorized as a terrorist group (its military wings at Shia_Crescentleast) by most governments around the world. Strategically, Russia can be considered an ally, but that nation is struggling in the face of western sanctions for its involvement in the Crimea and a falling oil price. (For a discussion of how falling oil prices are influencing foreign policies in Russia and Iran, see here). Iran is looking for new partners in China and India by offering them energy security; but this venture will be unlikely to result in any serious partnerships, especially if this partnership would result in possible international retaliations by the West. Iran is therefore left to defend itself against a myriad of threats. In this case, a nuclearized Iran can protect itself, or so the Iranian leadership believed, from military blackmailing. At the same time, Iran can project its power in what is known as the “Shia Crescent”, an area encompassing Iran, Iraq, Syria, and Lebanon, shaping itself into a regional power. Iran believes that thus nuclear power adds more muscle to its voice in regional and international affairs.

Needless to say, no matter what the reasons are for Iran’s acquisition of nuclear power, the rest of the world cannot be happy about the emergence of another potential nuclear power. However, the present countries that possess nuclear powers are in fact rebuilding their own respective nuclear arsenals even while they are denouncing the Iranian’s attempts to do so. We see that the rest of the world has been upgrading their own nuclear arsenals as well. In a recent article on Business Insider, the dangers of a nuclear war is emphasized more than ever before. However, the difference is that Iran is widely seen as an irresponsible government, and weapons in the hands of such a state is a worrying fact. But how should the rest of the world respond to it? Along the lines of journalist Fareed Zakaria, I believe that there are two main ways for the world to respond: 1. Forcing a Regime Change, or 2. Forcing a Policy Change. Let’s briefly define what each option meant and discuss their relative merits later:

  1. Regime Change:

In essence this would involve the fomenting of dissent, support democratic political movements, and with outside help in trying to overthrow the government of Iran in one form or another. Most likely, the United States would be the leader in such an effort. In the meanwhile, the US and other parts of the world should not have anything to do with Iran since it is an illegitimate government in their eyes. In the views many, the only way to properly address the nuclear situation with Iran is wait (or help) the government to change and then deal with them later.

  1. Policy Change:

This would mean that we will actively engage with the present government of Iran, treating them as an equal partner in these discussions, and really accept the fact that the government of Iran, however repulsive, is here to stay for some time to come. The dialogues will be conducted in an open manner and be peaceful in trying to reach a deal with Iran. For supporters of this option, they do not believe that this is a policy of appeasement, but rather, a step-by-step method toward achieving our objective, whatever they may be.

As a sophomore in college, I may not be in the best position to recommend foreign policy to those in the highest levels of government. But, nevertheless, I believe that here in the US and the rest of the world that does not desire to see a nuclearized Iran, have to decide on an option fast and not to oscillate back and forth between these two options. How can you possibly struck a deal with a government that you have every intention to help overthrow? Personally, I believe that the best option remains to bring Iran back into the international system, which it had been an outcast member since 1979, and to engage with it in more direct dialogue. We need to bring in international partners, which must include China, India and Russia, to discuss options with the Iranians on what to do. We must make Iran as an equal partner in its negotiations and not treat it as a criminal state. We need to recognize Iranian interests and why they sought to nuclearize themselves and to stress our own positions and concerns in why we do not want to see a nuclear program: no, it is not that we desire to encircle Iran on all sides, and no it is not that we desire to see a weakened Iran that is susceptible to invasions at any given moment. There are too much distrust and misconceptions between Iran and the West at the moment, each is mistrusting the other’s intentions. Therefore, if we can build an international coalition on resolving the issue, we can legitimize our intentions and make the Iranians understand that it is in the interest of the rest of world for them to denuclearize.

Current policies in delaying Iran’s nuclear programs have many merits to them. Firstly, the alternative, that of calling Iran to immediately destroy their nuclear facilities, will only strengthen their resolves in continuing to build them. If not in open, then in secret. Therefore, delaying what Iran has been attempting to do, by years (a very possible prospect), leaves the rest of the world with more options in dealing with the government. But more importantly, it buys the rest of the world time. The structure of government itself may likely change with the passage of years. I do not necessarily mean a revolution, but rather a gradual process of liberalization that will see a new generation of Iranian leaders that do not want to confront the world and or is filled with xenophobia, but rather sought peaceful coexistence. Younger generations of Iranian do not have the fervors of religious fanaticism that may have characterized some of their parents; in fact, I believe that many young Iranians today want to embrace the international system and be a part of modern society. I believe that will the passage of time, Iran can be a more responsible stakeholder in the international system and we can work with Iran toward this issue. However, in order to do this, we must first talk openly with Iran.

The importance of continuing dialogue with Iran cannot be overstated. If left isolated, Iran will retreat into itself and develop and deepen a paranoia of the rest of the world and perhaps the unthinkable will happen: a nuclearized Iran ready to use its weapons on its neighbors and beyond. As a historical analogy, imagine what if Henry Kissinger had never traveled to China to open up dialogue with that secluded nation, China today would possibly have been another North Korea: a government that is isolated and clung to an outdated ideology with a belligerent attitude toward the rest of the world. But to the credit of the US government (both the executive and the State department), rather than seeing this happen, the US government actively engaged with Chinese leadership and brought China into the international community of nations; a community that China has a stake in. In a similar line, I believe that by keeping the dialogue option open with Iran, we can hope to make some progress. Of course, this can only happen with Iranian commitment as well, and it needs to tone down the rhetoric against its neighbors and their allies, most notably Israel and the United States; it needs to show real commitment in following through with its promises; but above all, Iran needs to see that it is to its own security and benefit that it becomes a part of the international system rather than a challenger to it. Perhaps, eventually, Iran will be able to develop its own peaceful nuclear program, much as how Japan and South Korea has developed them, without feeling the need to weaponize it. All of these will likely take an enormous amount of time, likely decades; but I believe that in the end, the path of continued negotiations and dialogues with Iran will be preferable to any other alternative.
